a) The MOH Amplifier can receive programs from AUX
1 - AUX 2 and the MODULE.
b) Selection of the input source is by Internal Jumper.
c) The ZONE 1 independent 600 Ohm and 8 Ohm
Outputs may be used simultaneously.
d) The MOH 600 ohm Output is Transformer Balanced.
e) The Rear Panel ZONE 1 Level Control operates both
the 600 Ohm and 8 Ohm Outputs simultaneously.
MOH AND ZONE 1-2 OPERATION ISSUES
1) Paging from the Microphone Inputs or the Telephone
Input does not effect the MOH/ZONE 1-2 Amplifier.
2) Position of the INPUTS Level Control does not affect the
MOH/ZONE 1-2 Amplifier Output Level.
3) Position of the AUX 1 and AUX 2 ATTENUATOR does not
affect the MOH/ZONE 1-2 Amplifier Output Level.
4) Muting activation of M1 or M2 Buss (from Microphones or
Telephone) does not effect the Output of the MOH/ZONE 1-
2 Amplifier except if the INPUT SOURCE is set to MODULE
and the Module Output is Muted. See Module Settings.
